What the heck is bias anyway?


I'm getting a new tube amp that will need to be biased. The process of doing it seems fairly straight forward, but I am curious: what are you actually doing when you bias an amp? In english, for us technical Ludites.

So it's basically adjusting the current to the tube to make sure the appropriate amount of juice is getting in and out of it. Not too much, and not too little. I think I have it.

Thanks Elizabeth!
Cary v12. Apparently you can use a meter, or just turn the screws until the lights come on. Seems easy enough.
Well, whatever the hell it is, it sounds really nice!

Thanks for the answers and food fight! :-)
